Bug 60023 – Web Inspector: [Chromium] Expanding Summary view top-level nodes is very slow when the number of heap objects is high

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

[Mikhail Naganov]

The most frustrating part is that even if object count is small, it expands slowly. This is because for every class we iterate through all nodes.
